I like to wrap my getQuotes() calls in a while() loop to keep trying until I
get a valid quote:

Year <- 1970
currentYear <- as.numeric(format(Sys.time(),'%Y'))
while (Year != currentYear) {
         currentQuote <- getQuote('SPY')
         Year <- as.numeric(format(currentQuote['Trade Time'],'%Y'))
}
